Sunflower sea stars (commonly called starfish) are dying off by the millions on the Pacific Coast from Sea Star Wasting Disease. New Cornell-led research suggests that starfish, victims of sea star wasting disease (SSWD), may actually be in respiratory distress – literally “drowning” in their own environment – as elevated microbial activity derived from nearby organic matter and warm ocean temperatures rob the creatures of their ability to breathe. Cases are now reported from Mexico to Alaska with a spring … Researchers still can’t explain exactly what caused the massive die-off, though they think it could be linked to climate change, according to OPB. Deepening … Some researchers think the culprit could be a viral pathogen, but evidence is inconclusive. New Cornell University-led research suggests that starfish, victims of sea star wasting disease (SSWD), may actually be in respiratory distress—literally "drowning" in their own environment—as elevated microbial activity … Some of the species stand at the brink of extinction. Scientists have been eager to find the root cause of sea star wasting syndrome because the disease can lead to large die-offs. By the end of October, virtually all the SUNFLOWER STARS were dead. The combination of symptoms that have been collectively described as “sea star wasting disease” is believed to be a strong factor. Share this: Share on Flipboard The syndrome is a general description of symptoms found in affected sea stars. 2016;11(4): e0153670. For more than seven years, a mysterious wasting disease has nearly killed off sea star populations around the world. Some of these species stand at the brink of extinction. Sea star wasting disease describes a condition affecting asteroids that resulted in significant Northeastern Pacific population decline following a mass mortality event in 2013. This catastrophic event that has decimated many species of starfish and begun to affect other tidepool animals. When was sea star wasting disease first noticed? Melissa Miner, a researcher in the Department … Some of these species stand at the brink of extinction. Becker BJ. Tissue samples … While SUNFLOWER STARS bore the brunt of the disease, other stars were also dying, including the MORNING SUN STAR Solaster dawsoni, … Scientists aren’t sure what causes this disease, known as sea star wasting syndrome (SSWS). Sea Star Wasting Disease or Syndrome. The syndrome, linked to a virus, starts as white lesions on the sea stars, but … The first reports of sea star wasting disease were from June 2013 in the Pacific Northwest and Southern California. New Cornell University-led research suggests that starfish, victims of sea star wasting disease (SSWD), may actually be in respiratory distress—literally “drowning” in their own environment—as elevated microbial activity … Decreased temperature facilitates short-term sea star wasting disease survival in the keystone intertidal sea star Pisaster ochraceus. Previous work suggested that sea star-associated densovirus (SSaDV) was the best candidate pathogen responsible for sea star wasting disease (SSWD) among about two dozen species affected by it. Some of these species stand at the brink of extinction. The study confirms that sea star species suffered unequally during the outbreak, and reveals that at least one species benefitted from diminished … Some of these species stand at the brink of extinction. Sick sea stars were found all the way from Baja California to southern Alaska, although not in … A mysterious wasting disease has nearly killed off sea star populations around the world. New Cornell-led research suggests that … A November 2014 study pointed to a virus which spreads within entire populations, called 'sea star associated denso-virus' Recent, abnormally warm water temperatures in some areas along the West Coast are likely stressing sea stars and … The etiology of sea star wasting is unresolved. To pinpoint the suspected biological agent, Cornell researchers devised a laboratory experiment using sunflower sea stars (Pycnopodia helianthoides) that showed symptoms of Sea Star Wasting Disease. The wasting disease was first noticed in ochre sea stars along the coast of Washington in June, 2013. New research suggests the new sea star populations may be evolving to promote genetic resistance to the virus causing the wasting disease. In this paper, we present evidence that the cause of the disease is transmissible from disease-affected animals to apparently healthy individuals, that the disease-causing agent is a virus-sized … View Article PubMed/NCBI Google Scholar 21. The research, “Evidence That Microorganisms at the Animal-Water Interface Drive Sea Star Wasting Disease,” was published in the journal Frontiers in Microbiology.
